[Closed] Oval rings - recent 1x reviews

Holy thread resurrection batman....

I'm particularly interested if anyone with dodgy knees can report back on the performance on these, it's been suggested in some of their promotional material that it can help but not seen anything mentioned here or in other tests.
I have a variety of knee issues (ACL, meniscus, bone damage) that cause minor knee niggles when riding- Mainly slight knee popping on every pedal stroke and pain on occasion.
Just wondering if something like this might be beneficial for them?
